For those thinking of generating electricity from the sun but have looked at the cost and cannot see a how the return on investment works!

There are now several companies offering to fit and maintain photovoltaic cells for "free" but you need to look VERY closely at the T&C's some of them try to lock you in to a 25 year contract even if you sell the property! I'm not sure this is enforceable but it will cause a lot of trouble when or if you move!!
